Not the best idea... hahaha. Don't martyr yourself - we need all the freedom-minded individuals we can get.
In addition (and I'm reluctant to admit this because immoral people piss me off to no end), we should remember that morality is merely a distillation and codification of the one universal law of interaction between living beings - LOVE. The best case scenario is that police (and all who act immorally) will be made to see the error of their ways, not that they'll be killed. Punishment is of no value, though defense is necessary. Regardless of what they may have done to this point, if they can be turned around, we are obliged by moral law to embrace that option. As annoying as that is, it's just the way of things.
